TYFEWBITI NG MACHINE;

Application filed January typewriting machines of the continuous billing or fan-fold type disclosed in the W'er nel y & Sm tent N0. ,13 9 da March 16, 1915, andmore particularly the, lDVGIltlOIl relates to, meansv to accommodate a pluralityof sets vofwork-webs which may be typed individually.

Machines have beenprovided to accom modate separate work-webs; but this has usually required considerable change instructure, and in some instances more space.

An object of the present invention is to adapt the Underwood continuous billing machine to this kind of workwith a mini? mum of change in constructon and without requiring additional space. I

In carrying out the invention, separate carbon-carriers are provided for each set of webs, and these carbonecarriers are detachably supported on the steps which usually irry carbon-carryingblades in said lVernery & Smith patent. There may be two, three or tour webs in the machine, usually only one ofthem beingtyped at a time. The webs which are not in use may be folded back between the carbon-carriers, so, as not to interfere with manipulation of the active Web.

Each carbon-carrier is composed ot two blocks, one at each side,v said blocks being connected to each other by a bridge or crossbar. Each block may he composed of one or more steps upon which suitable carbonarrying blades are detachably mounted. Each carbon-carrieris, provided with means. for detachably mounting it on the carboncarrier truck. To this end there are provided resilient devices, which are herein shown on the Qarbou carrier, to engage the truck in a suitable manner to hold the carboncarrier agal 1st accidental removal. In one form of the invention these devices are in the nature of split pins on the carbon-can rier to engage in holes in said truck, whereby each carbonrarrier may be readily detached from the truck "for the substitutimi of another set of webs and its individual carbonce rrier.

The carbon-carriers may vary in size, their capacity being determined by the number of steps. They may be arranged in any desired order on the steps of the truck, and the as, 1925. Serial No. 5,212..

one associated with the web, used mostffrequently may be arranged at the top of the 'set.

Inanotherfor-m of the invention there are provided a main carboincarrier and another carbon-carrier detachably mounted thereon. Each of said carbon-carriers is provided with a series of steps upon which the carboncarrying bladesare supported. The carhon-ccarriers are also arranged in stepped relation with respect to each other. With this arrangement the detachable carbon-carrier may be used for a separate web. independently of the web associated with the main carbon-carrier or it may be used to increase the capacity of the main carbonecarr-ier. To attach the carbon-carrier, of the lastnamed form of the invention, it is provided with two arms, each arm being bifurcated to form two resilient fingers to spring over a stud orscrew on the main carbon-carrier.

Said screws may be used to secure in place suitable side gages co-operating with the webs. y y g a Other features andadvant-ages will hereinafter appear. p I i In the accon'ipanying drawings,

Figure 6 is a fractional PGI'SPQCUVQ View of a six-blade v carbon-carr'ier, illustrating the method of attaching the same to the regular carrier. and. showing the carboncarrying blades.

The fanefold typewriting machine comprises a carriage upon which there is revolubly mounted a platen 10 displaceable ion wardly away from its co-operating feed-rolls 1 by the type-bars 13 in front thereof. At the rear end of the platen there is provided a frame forming part of the carriage and supported at its rearmost end by a crossbar fast to the frame of the machine. The rear frame comprises rails 14 upon which a carbon-carriage 15 is slidably mounted on wheels 16 pivoted on said carbon-carriage.

There may be plurality of webs on the machine, each of the webs having a plurality of plies, and the plies being interleaved by sheets of carbon-paper. However, only one of the webs may be typed upon at one time, and while typing upon one the other webs 53 are folded back between the carhon-carrying blades.

The active web is indicated by the numeral 17 in Figure l, and isshown over a cross-bar 18 between guides 19 and is passed over the carbon-carriage by interleaving the plies 20 of the web with sheets of carbon-paper 21 having their rear ends fast to carbon-carrying blades 22. The leading edge of the web is pulled forward over a rear table 2-3, down and under the platen to engage with the teed-rolls, and up around the platen over a front table, not shown.

When it is desired to write upon any other web the active web is then Withdrawn from engagement with the platen and is folded back as shown in Figure 2 in which another web 2% is shown threaded between the carbons and around the platen.

One of the features of this invention is the provision ol means whereby webs containing a dififerent number of plies may be used on a standard machine having a single carbon-carrier and truck, and to this end there is provided a plurality of auxiliary carbon-carriers which may be attached to the regular carrier disposed to carry any number of carbon blades to suit the number of plies ot the web. in one form of this invention the auxiliary carbon-carriers, as shown in Figures 1, 9-, and 6, are attached to the regular carbon-carriers 25 by means of split pins 26 fitting.into the holes 27 which normally hold the carl'ion-blades. Although there are provided two pins at each end "for holding the auxiliary carbon-carriers on the regular carbon-carrier. it is obvious that one at each end would also effectively hold the carriers in place. due to the cross-bar connecting the two end blocks. In Figure 5 the auxiliary carbon-carriers are illustrated of different capacities, that is to say, for carryingeither two, tour or six carbon-sheets, and all being interchangeable With one another, so that the web which is used more often may be placed at the top, where it is handier to operate. in removing any of the auxiliary carriers from the truck for substitution of another set of webs, it will be noted that the carbon-blades associated with any set always remain rigid supporting extensions.

in working position with. relation to one another. This facilitates removal and attachment of: different web sets by reason of the fact that the group of carbons and blades used with each Web set is alive properly held in place. A carbon-carrier in its simplest form is illustrated comprising two carbon-carrying blades 28 mounted on blocks 29 tied together by a connecting piece 30. T

.ie carbon-carrying blades are detachably fastened thereto in a manner as shown in Figure 6, in which the carbonblades are provided with two downwardly extending pins 38 engaging with holes 31 in the carbon-carrier. The carbon-carrier blades used with the auxiliary carboncarriers are the same as used in the regular machine, and comprise a supporting blade 32 and a locking blade 33, the latter being pivotally mounted on a finger-piece 34:. The tour-blade auxiliary carbon-carrier is illustrated in Figure 5, and comprises two end blocks 35 and a connecting piece 36. The blocks are provided with the downwardly-extending pins 526 engaging with the holes 27 in the blocks 37 of the carrier 25, and extend to the rear forming a higher step 39 disposed to carry a second set of carboncarrying blades. Said blocks 35 are wider than the blocks 37, and are hollowed, as indicated in Figure 6 by the numeral l0, tor the purpose of clearing the steps ll of the blocks 37. The six-blade auxiliary carrier, shown in Figure 5, is the same as the tourblade carrier previously described, with the exception of a third step l2 provided to carry the extra blades 22 detachably mounted thereon. It will be noted that in Figure l the same auxiliary carbon-carriers are shown, and are disposed relatively to the regular carrier in the same manner as il-' lustrated in Figure 5, and that in Figure 2 the same auxiliary carbon-carriers are shown, but are differently disposed in relation to the regular carrier.

In another term of this invention the auxiliary carbon-carriers are mounted at the rear of the regular carrienaud the modification illustrated in Figures 3 and 4. Said auxiliary carriers comprise a horizontallydisposed cross-bar l-l having two downwardly-extending supporting extensions L5, one at each end. and said extensions termi nating in a forlr having two prongs 46. designed to be snapped over the screws 47. normally holding the side gages 48, and into which a. groove is out to receive the 7 At both ends ot the cross-bar 44-. there are provided blocks 54 designed to receive the carbon-carryiug blades shown in Figure 3. Fluid blades are provided with the usual pins which enter the holes 51. it will be noted that the screws 47, supporting this type oi auxiliary carrier. are made special and substitute the renular screws 52 shown in El ures 1 and 2. c i i g Valuations may bere'sorted to within' the scope o-f'the invention, and portions of the improvements may beused without others.
